Physical security. Litter the area with cameras, possibly in several mutually independent networks. It is impossible to get physical access to the computer without being seen. Don't forget battery backups. A hardware keyboard logger is sometimes a friend, especially if built right onto the motherboard. The computer's case can be welded-shut, preventing easy access to the disks and slowing down the adversaries. Another measure could be a computer sniffing and logging all communication to/from the computer over the LAN, into a circular buffer, allowing forensic analysis of any communication that was potentially improper. This serves as security camera guarding the network access. Similarly, the kernel on the protected machine itself can log accesses to certain parts of filesystems or physical block devices, and prevent loading of modules that aren't cryptographically signed. ...of course, a shotgun as an active defensive device has its certain appeal. However, there are usually more blackbaggers than one, and computer aiming could be unreliable against fast-moving panicking targets, so a nerve gas should be considered an option. (If you aren't in a killing mood, a tear gas could do its job too. A device that would pierce a spray can with a self-defense paralyzer, quickly dispersing it in the room, could theoretically work nicely too.) A good area denial device could MAYBE be a device made from teflon and magnesium strips; teflon pyrolysis products are reportedly pretty toxic; but I am just wildly speculating here and inviting discussion about the weak sides of my ideas. The shotgun could also serve as a quick data destruction device; imagine what a swarm of fast-flying steel balls can do with disk plates spinning on 10,000 rpm. If the impact primer will be replaced with electrically controlled one, even better - the system then has no moving parts and gets inherently more reliable and maintenance-free. The barrel could be improvised from a piece of a steel pipe, with a suitable length to allow the payload from the shells to reach suitable velocity to shred the plates, attached on the disk over its top side which is usually fairly thin aluminum. If anyone would be willing to test the idea on some discarded drives (*wink, Tim*) I would be happy to know the results. Would "Lead Wipe" be a suitable name for this technology?
